  • FDT is a manufacturer-independent and fieldbus-independent concept in automation technology, which enables the operation and in particular the parameterization of different field devices from different manufacturers and different fieldbuses with a single program.
  • FDT is a specification for a software interface. This software interface describes the data exchange between an application and software components for the field devices.
  • FDT is standardized as International Standard IEC62453 and ISA103.
  • FDT is used both in process engineering plants and in factory automation.
  • the concept supports both simple field devices (with few parameters) as well as complex devices (with many parameters and modules).
  • FDT pursues the essential goal of using the various device software, eg. B. Merge device driver DTMs in a common frame application (FDT Frame Application). From this central frame application, the various field devices can be accessed and the corresponding device DTMs used to configure the associated physical devices.
  • B. Merge device driver DTMs in a common frame application (FDT Frame Application). From this central frame application, the various field devices can be accessed and the corresponding device DTMs used to configure the associated physical devices.
  • FDT supports a large number of communication protocols as well as communication across nested network protocols.
  • DTMs can be used system-independently in various frame applications.
  • a "Device Type Manager” corresponds to a device-specific software component that processes data for the device.
  • a DTM includes a logic device driver component, which provides all the functions, structure, and parameterization of the field device, as well as a user interface device driver component that provides a user interface for a particular field device or for a device family.
  • DTMs are installed like a program on a computing unit, but can only be used from within the framework application.
  • DTMs for field devices there are also DTMs for communication connections (communication DTMs), for example for bus interface cards or HART modems.
  • communication DTMs implemented the fieldbus-independent part of the FDT concept.
  • a client application that runs on a handheld terminal communicates with a control program for field devices or a field device management module that runs on a larger computer unit such as workstation via a service-service interface.

  • the logic device driver components DTM-BL can exchange data with the field devices D1... Dn via the communication drivers CDTM1... CDTMk and possibly further drivers DD1, DD2.
  • the logic device driver components DTM-BL can be derived from DTM packets DTM-P1 ... DTM-Pk which are stored in an embedded DTM catalog MDTM-C or are available for download.
  • the Embedded Server Frame Application SFDT-FA is a particular implementation of the well-known FDT Frame Application, which is designed for use without FDT user interface, if only the DTM BLs of the device drivers are used. Thus, this can also be optimized and used for resource-limited systems. This results in reduced hardware costs and optimized performance.
  • the advantage is achieved in particular that the embedded server frame application does not require user interfaces, since these are provided by the server S and displayed in the operating device BG.
  • the field device management module FMM may be configured as a single-board computer such as Raspberry Pi, i. without user interface and with a "Plug & Play" concept for installation.
  • server frame application with device driver logic DTM-BL is embedded in a control device such as SPS. This would eliminate the need for additional hardware to connect to a FDT configuration level.
  • the embedded server-frame application may also run on a specific FDT microcontroller chip located in a control unit such as a PLC or a device capable of handling an FDT task. This would have the advantage that the main operating procedure of a control is not influenced or disturbed, since the FDT-based processes at the hardware level would run separately from each other.
  • the Fig. 6 to 8 12 schematically show interaction and communication mechanisms for providing device driver packets DTM-P or communication device driver packets CDTM-P for devices ND such as field devices or gateways newly connected to the fieldbus FB and for which no corresponding device driver -Packet DTM-P, CDTM-P is installed on the local system FMM.
  • Fig. 6 shows the approach for the central provision of the device driver packages DTM-P1 ... DTM-Pn for a newly connected to the fieldbus FB field device ND.
  • the new field device ND is connected to the fieldbus FB.
  • a search is made for the new field device ND in the plant topology.
  • the new field device ND is checked in a third step, whether a suitable device driver package DTM-P for the new device ND is available.
  • the search is performed in the device driver catalog SDTM-C associated with the web server WSER to install the corresponding user interface device driver components DTM-UI and to display the user interface.
  • the availability of the logic device driver DTM-BL is checked in order then to install it in a fifth step in the embedded FTD server frame application SFDT-FA, if this is not yet available.
  • the DTM-BL logic device driver component is installed by replacing the complete DTM-P device driver package from the SDTM-C Web server catalog with the MDTM-C embedded catalog of the FMM field device management module.
  • Fig. 7 1 schematically shows an approach for providing a device driver packet DTM-P in a server-side device driver catalog SDTM-C from a decentralized DTM catalog DTM-C of a decentralized network DN such as cloud.
  • the new device ND After the new device ND has been connected to the fieldbus FB in a first step and the new device ND has been found by the operating device BG in a second step, in a third step the availability of a device driver packet DTM-P in the device driver catalog SDTM-C of the server S checked.
  • a connection to the DTM DTM catalog DTM-C is set up in a fourth step, i. an external memory in which the device driver packages DTM-P1 ... DTM-Pn are stored and can be loaded. If no suitable device driver package DTM-P is found there either one of the generic device drivers GCDTM can be used.
  • the corresponding device driver packet DTM-P from the DTM catalog DTM-C is loaded into the server-side DTM catalog SDTM-C and installed in the FDT client frame application CFDT-FA of the server S, to be able to provide the user interface UI for the new device as a web page through the web server WSER.
  • the device driver package DTM-P is loaded and installed in the embedded FDT server frame application SFDT-FA, so that the corresponding logic device driver component DTM-BL can be used.
  • Fig. 8 shows a schematic representation of an approach for the distributed provision of device driver packets DTM-P1 ... DTM-Pn. If the device driver package DTM-P can not be found in the DTM catalog SDTM-C of the server S, then in a fourth step the search for device driver packages DTM-P in further field device management modules FMM with embedded FDT Server Frame Applications SFDT-FA and Embedded DTM Catalogs MDTM-C. After finding a suitable device driver packet DTM-P this is loaded from the field device management module FMM in the device driver catalog SDTM-C of the server S and in a sixth step in the embedded FDT server frame application SFDT-FA of the field device management module FMM to which the new device ND is connected.
  • DTM-UI user interface device driver components
  • DTM-UI user interface device driver components
  • conventional WPF based UI device driver components are known for legacy applications.
  • web-based packages based on web technology are also known.
  • combination packages containing both a conventional component and a web-based component are also known.
  • This invention assumes a device driver package with at least one web-based user interface device driver component.
